我有一个登陆页面：我是这样用它的，肯定错了。如何用？
private void Page_Load(object sender, System.EventArgs e)
{
showProgress();//WEB应用程序中的进度条 if(!IsPostBack)
{
loginbtn.Attributes.Add("onmouseover","this.src='images/logindown.gif'");
loginbtn.Attributes.Add("onmouseout","this.src='images/login.gif'");
}
}
private void loginbtn_Click(object sender, System.Web.UI.ImageClickEventArgs e)
{
string script = @"<script language='javascript'>"
+"\r"
+"window.opener=null;window.close();var Win = window.open('Webui/main.aspx','main','fullscreen=yes');\r"
+"Win.moveTo(0,0);\r"
+"Win.resizeTo(screen.width,(screen.height-25));\r"
+"</script>";
Response.Write(script);
}
private void showProgress()
{
string strFileName = Path.Combine( Server.MapPath("./Progress"), "progressbar.htm" );
StreamReader sr = new StreamReader( strFileName, System.Text.Encoding.Default );
string strHtml = sr.ReadToEnd();
Response.Write( strHtml );
sr.Close();
Response.Flush();
Thread thread = new Thread( new ThreadStart(ThreadProc) );
thread.Start();
thread.Join();
}
private void ThreadProc()
{
//其中的{0}会被相应的i替换，而该段脚本会调用预先写好的javascript函数setPgb，更改页面的进度条状态。
string strScript = "<script>setPgb('pgbMain','{0}');</script>";
for ( int i = 0; i <= 100; i++ )
{
System.Threading.Thread.Sleep(10);
Response.Write( string.Format( strScript, i ) );
Response.Flush();

在实际项目中可以根据后台程序执行的进度往前端发送脚本To:IamBird(IamBird)
不可能的吧，我已经运行正常，没有问题的，把你的代码贴出来我看看吧
